Advanced experiments in 4-D Printing in Boulder
By Staff on November 15, 2013
Researchers led by H. Jerry Qi, an associate professor at the University of Colorado Boulder, is using heat and mechanical pressure to transform flat objects into three-dimensional structures. They printed an unfolded box with glassy polymer fibers — a composite material that has “shape memory behavior” — along the folds. They heated it, pulled on the sides and cooled it, and the flat structure responded by folding into a box.
